Default Structural and dynamic studies of DNA recognition by NF-?B p50 RHR homodimer using methyl NMR spectroscopy

Structural and dynamic studies of DNA recognition by NF-?B p50 RHR homodimer using methyl NMR spectroscopy

Protein dynamics involving higher-energy sparsely populated conformational substates are frequently critical for protein function. This study describes the dynamics of the homodimer (p50)2 of the p50 Rel homology region (RHR) of the transcription factor NF-?B, using 13C relaxation dispersion experiments with specifically (13C, 1H)-labeled methyl groups of Ile (?), Leu and Val. Free (p50)2 is highly dynamic in solution, showing ?s-ms relaxation dispersion consistent with exchange between the...

NMR: an essential structural tool for integrative studies of T cell development, pMHC ligand recognition and TCR mechanobiology
NMR: an essential structural tool for integrative studies of T cell development, pMHC ligand recognition and TCR mechanobiology Abstract Early studies of T cell structural biology using X-ray crystallography, surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) focused on a picture of the αβT cell receptor (αβTCR) component domains and their cognate ligands (peptides bound to MHC molecules, i.e. pMHCs) as static interaction partners. Moving forward requires integrating this corpus of data with dynamic technologies such as...

Measuring the signs of the methyl 1 H chemical shift differences between major and â??invisibleâ?? minor protein conformational states using methyl 1 H multi-quantum spectroscopy
Measuring the signs of the methyl 1 H chemical shift differences between major and â??invisibleâ?? minor protein conformational states using methyl 1 H multi-quantum spectroscopy Abstract Carrâ??Purcellâ??Meiboomâ??Gill (CPMG) type relaxation dispersion experiments are now routinely used to characterise protein conformational dynamics that occurs on the μs to millisecond (ms) timescale between a visible major state and â??invisibleâ?? minor states. The exchange rate(s) ( \( k_{{{\text{ex}}}} \) ...

3D-TROSY-based backbone and ILV-methyl resonance assignments of a 319-residue homodimer from a single protein sample
3D-TROSY-based backbone and ILV-methyl resonance assignments of a 319-residue homodimer from a single protein sample Abstract The feasibility of practically complete backbone and ILV methyl chemical shift assignments from a single -labeled protein sample of the truncated form of ligand-free Bst-Tyrosyl tRNA Synthetase (Bst-Î?YRS), a 319-residue predominantly helical homodimer, is established. Protonation of ILV residues at methyl positions does not appreciably detract from the quality of TROSY triple resonance data. The assignments are performed at 40 °C to improve the sensitivity of...

Automated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methylâ??methyl nuclear overhauser enhancement spectroscopy
Automated sequence- and stereo-specific assignment of methyl-labeled proteins by paramagnetic relaxation and methylâ??methyl nuclear overhauser enhancement spectroscopy Abstract Methyl-transverse relaxation optimized spectroscopy is rapidly becoming the preferred NMR technique for probing structure and dynamics of very large proteins up to ~1 MDa in molecular size. Data interpretation, however, necessitates assignment of methyl groups which still presents a very challenging and time-consuming process. Here we demonstrate that, in combination with a known 3D structure, paramagnetic...
